Surprisingly, that is a serious question, as a man who thought he bought
a toy poodle at Argentina's largest bazaar found out that he had gotten
a ferret instead:

Gullible bargain hunters at Argentina's largest bazaar are forking
out hundreds of dollars for what they think are gorgeous toy poodles,
only to discover that their cute pooch is in fact a ferret pumped up
on steroids.

One retired man from Catamarca, duped by the knock-down price for a
pedigree dog, became suspicious he had bought what Argentinians call
a 'Brazilian rat' and when he returned home took the 'dogs' to a vet
for their vaccinations.

Imagine his surprise when his suspicious were confirmed - he had in
fact purchased two ferrets that had been given steroids at birth to
increase their size and then had some extra grooming to make their coats
resemble a fluffy toy poodle.
